The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. (CVE-2020-36516)\n\n - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\n\n - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. (CVE-2022-1012)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)\n\n - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-223375145References: Upstream kernel (CVE-2022-20369)\n\n - A flaw in net_rds_alloc_sgs() in Oracle Linux kernels allows unprivileged local users to crash the machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice.

The mixed IPID assignment method with the\n hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session\n or terminate that session. (CVE-2020-36516)\n\n - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and\n SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a\n user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\n\n - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the\n small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of\n service problem. (CVE-2022-1012)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel\n (CVE-2022-20368)\n\n - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input\n validation. This could lead to local escalation of privilege with System execution privileges needed. User\n interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-223375145References: Upstream kernel (CVE-2022-20369)\n\n - A flaw in net_rds_alloc_sgs() in Oracle Linux kernels allows unprivileged local users to crash the\n machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector\n (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation\n (CVE-2022-2588)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow\n an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of\n actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()\n function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This\n flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and\n incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted\n IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to\n cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14\n and later versions. (CVE-2022-29581)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where\n virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-\n free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)\n when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to\n potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read\n and copying it into a socket. (CVE-2022-3028)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in\n net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race\n condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale\n TLB entries. This only occurs in situations with VM_PFNMAP VMAs.

The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. (CVE-2022-1462)\n\n - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-182388481References: Upstream kernel (CVE-2022-20166)\n\n - A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171) (CVE-2022-21505)\n\n - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges.

Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.

(CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of\n actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()\n function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This\n flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to\n cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14\n and later versions. (CVE-2022-29581)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create\n user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to\n a use-after-free. (CVE-2022-32250)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote\n attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte\n nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",

referenced in the SUSE-SU-2022:3450-1 advisory.\n\n - The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set. (CVE-2016-3695)\n\n - A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl() printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had been freed by gprinter_free(). (CVE-2020-27784)\n\n - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. (CVE-2020-36516)\n\n - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them. (CVE-2021-4155)\n\n - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\n\n - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. (CVE-2022-1012)\n\n - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-182388481References: Upstream kernel (CVE-2022-20166)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)\n\n - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-223375145References: Upstream kernel (CVE-2022-20369)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data. (CVE-2022-2905)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.

(CVE-2022-0617)\n\n - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\n\n - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1048)\n\n - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)\n\n - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub- component.

Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is disabled by default, it could allow an attacker to crash the system or have other memory-corruption side effects.

(CVE-2022-21499)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor. (CVE-2022-24448)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - In drivers/hid/hid-elo.c in the Linux kernel before 5.16.11, a memory leak exists for a certain hid_parse error condition. (CVE-2022-27950)\n\n - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.\n (CVE-2022-28390)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state. (CVE-2022-28893)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.

This\n flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and\n incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted\n IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)\n\n - A flaw was found in hw. Mis-trained branch predictions for return instructions may allow arbitrary\n speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-23816)\n (CVE-2022-28693)\n\n - An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller\n driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input\n data. This flaw allows a local user to crash the system. (CVE-2022-2873)\n\n - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the\n bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to\n gain unauthorized access to data. (CVE-2022-2905)\n\n - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is\n disabled by default, it could allow an attacker to crash the system or have other memory-corruption side\n effects. (CVE-2022-2938)\n\n - A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring().\n The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper\n locking when performing operations on an object. This flaw allows a local user to crash the system or\n escalate their privileges on the system. (CVE-2022-2959)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where\n virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-\n free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)\n when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to\n potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read\n and copying it into a socket. (CVE-2022-3028)\n\n - An issue was discovered in the Linux kernel through 5.16-rc6. There is a lack of check after calling\n vzalloc() and lack of free after allocation in drivers/media/test-drivers/vidtv/vidtv_s302m.c.\n (CVE-2022-3078)\n\n - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create\n user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to\n a use-after-free. (CVE-2022-32250)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in\n net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote\n attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte\n nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race\n condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale\n TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of\n service can occur upon binding to an already bound chain. (CVE-2022-39190)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",

advisory.\n\n - The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set. (CVE-2016-3695)\n\n - Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196.\n (CVE-2020-16119)\n\n - A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl() printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had been freed by gprinter_free(). (CVE-2020-27784)\n\n - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. (CVE-2020-36516)\n\n - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them. (CVE-2021-4155)\n\n - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)\n\n - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-223375145References: Upstream kernel (CVE-2022-20369)\n\n - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)\n\n - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data. (CVE-2022-2905)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system or potentially escalate their privileges on the system. (CVE-2022-3239)\n\n - A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or member of the audio group) could use this flaw to crash the system, resulting in a denial of service condition (CVE-2022-3303)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of service can occur upon binding to an already bound chain. (CVE-2022-39190)\n\n - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)\n\n - mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is not held during a PUD move.

(CVE-2016-3695)\n\n - Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP\n socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux\n kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196.\n (CVE-2020-16119)\n\n - A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl()\n printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had\n been freed by gprinter_free(). (CVE-2020-27784)\n\n - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the\n hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session\n or terminate that session. (CVE-2020-36516)\n\n - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size\n increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS\n filesystem otherwise not accessible to them. (CVE-2021-4155)\n\n - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and\n SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a\n user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel\n (CVE-2022-20368)\n\n - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input\n validation. This could lead to local escalation of privilege with System execution privileges needed. User\n interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-223375145References: Upstream kernel (CVE-2022-20369)\n\n - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to\n restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently\n allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass\n verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and\n unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for\n peripherals that do not verify firmware updates.

(CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of\n actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()\n function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This\n flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and\n incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted\n IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the\n bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to\n gain unauthorized access to data. (CVE-2022-2905)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where\n virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-\n free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)\n when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to\n potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read\n and copying it into a socket. (CVE-2022-3028)\n\n - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers\n em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system\n or potentially escalate their privileges on the system. (CVE-2022-3239)\n\n - A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead\n to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or\n member of the audio group) could use this flaw to crash the system, resulting in a denial of service\n condition (CVE-2022-3303)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in\n net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race\n condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale\n TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of\n service can occur upon binding to an already bound chain. (CVE-2022-39190)\n\n - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused\n by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)\n\n - mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is\n not held during a PUD move. (CVE-2022-41222)\n\n - drivers/char/pcmcia/synclink_cs.c in the Linux kernel through 5.19.12 has a race condition and resultant\n use-after-free if a physically proximate attacker removes a PCMCIA device while calling ioctl, aka a race\n condition between mgslpc_ioctl and mgslpc_detach. (CVE-2022-41848)\n\n - drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race condition and resultant use-\n after-free if a physically proximate attacker removes a USB device while calling open(), aka a race\n condition between ufx_ops_open and ufx_usb_disconnect.

A privileged local user could use this flaw to crash the system or escalate their privileges on the system.\n (CVE-2021-3640)\n\n - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.\n (CVE-2021-30002)\n\n - A denial of service (DOS) issue was found in the Linux kernel's smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.\n (CVE-2022-0168)\n\n - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)\n\n - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\n\n - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1048)\n\n - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)\n\n - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub- component. This flaw allows a local attacker with a user privilege to cause a denial of service.\n (CVE-2022-1184)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal instruction in guest in the Intel CPU. (CVE-2022-1852)\n\n - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code. (CVE-2022-2078)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is disabled by default, it could allow an attacker to crash the system or have other memory-corruption side effects. (CVE-2022-2938)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)\n\n - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.\n An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered. (CVE-2022-21499)\n\n - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information. (CVE-2022-23960)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor. (CVE-2022-24448)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - In drivers/hid/hid-elo.c in the Linux kernel before 5.16.11, a memory leak exists for a certain hid_parse error condition. (CVE-2022-27950)\n\n - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.\n (CVE-2022-28390)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state. (CVE-2022-28893)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.", "cvss3": {"exploitabilityScore": 1.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "baseScore": 7.8, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-11-14T00:00:00", "type": "nessus", "title": "AlmaLinux 8 : kernel (ALSA-2022:7683)", "bulletinFamily": "scanner", "cvss2": {"severity": "HIGH", "exploitabilityScore": 3.9, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.2, "vectorString": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "LOCAL", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2020-36516", "CVE-2020-36558", "CVE-2021-30002", "CVE-2021-3640", "CVE-2022-0168", "CVE-2022-0617", "CVE-2022-0854", "CVE-2022-1016", "CVE-2022-1048", "CVE-2022-1055", "CVE-2022-1184", "CVE-2022-1852", "CVE-2022-20368", "CVE-2022-2078", "CVE-2022-21499", "CVE-2022-23960", "CVE-2022-24448", "CVE-2022-2586", "CVE-2022-26373", "CVE-2022-2639", "CVE-2022-27950", "CVE-2022-28390", "CVE-2022-28893", "CVE-2022-2938", "CVE-2022-29581", "CVE-2022-36946"], "modified": "2022-12-13T00:00:00", "cpe": ["p-cpe:/a:alma:linux:bpftool", "p-cpe:/a:alma:linux:kernel", "p-cpe:/a:alma:linux:kernel-abi-stablelists", "p-cpe:/a:alma:linux:kernel-core", "p-cpe:/a:alma:linux:kernel-cross-headers", "p-cpe:/a:alma:linux:kernel-debug", "p-cpe:/a:alma:linux:kernel-debug-core", "p-cpe:/a:alma:linux:kernel-debug-devel", "p-cpe:/a:alma:linux:kernel-debug-modules", "p-cpe:/a:alma:linux:kernel-debug-modules-extra", "p-cpe:/a:alma:linux:kernel-devel", "p-cpe:/a:alma:linux:kernel-headers", "p-cpe:/a:alma:linux:kernel-modules", "p-cpe:/a:alma:linux:kernel-modules-extra", "p-cpe:/a:alma:linux:kernel-tools", "p-cpe:/a:alma:linux:kernel-tools-libs", "p-cpe:/a:alma:linux:kernel-tools-libs-devel", "p-cpe:/a:alma:linux:kernel-zfcpdump", "p-cpe:/a:alma:linux:kernel-zfcpdump-core", "p-cpe:/a:alma:linux:kernel-zfcpdump-devel", "p-cpe:/a:alma:linux:kernel-zfcpdump-modules", "p-cpe:/a:alma:linux:kernel-zfcpdump-modules-extra", "p-cpe:/a:alma:linux:perf", "p-cpe:/a:alma:linux:python3-perf", "cpe:/o:alma:linux:8", "cpe:/o:alma:linux:8::baseos", "cpe:/o:alma:linux:8::powertools"], "id": "ALMA_LINUX_ALSA-2022-7683.NASL", "href": "https://www.tenable.com/plugins/nessus/167447", "sourceData": "#%NASL_MIN_LEVEL 80900\n##\n# (C) Tenable, Inc.\n#\n# The package checks in this plugin were extracted from\n# AlmaLinux Security Advisory ALSA-2022:7683.\n##\n\ninclude('compat.inc');\n\nif (description)\n{\n script_id(167447);\n script_version(\"1.3\");\n script_set_attribute(attribute:\"plugin_modification_date\", value:\"2022/12/13\");\n\n script_cve_id(\n \"CVE-2020-36516\",\n \"CVE-2020-36558\",\n \"CVE-2021-3640\",\n \"CVE-2021-30002\",\n \"CVE-2022-0168\",\n \"CVE-2022-0617\",\n \"CVE-2022-0854\",\n \"CVE-2022-1016\",\n \"CVE-2022-1048\",\n \"CVE-2022-1055\",\n \"CVE-2022-1184\",\n \"CVE-2022-1852\",\n \"CVE-2022-2078\",\n \"CVE-2022-2586\",\n \"CVE-2022-2639\",\n \"CVE-2022-2938\",\n \"CVE-2022-20368\",\n \"CVE-2022-21499\",\n \"CVE-2022-23960\",\n \"CVE-2022-24448\",\n \"CVE-2022-26373\",\n \"CVE-2022-27950\",\n \"CVE-2022-28390\",\n \"CVE-2022-28893\",\n \"CVE-2022-29581\",\n \"CVE-2022-36946\"\n );\n script_xref(name:\"ALSA\", value:\"2022:7683\");\n\n script_name(english:\"AlmaLinux 8 : kernel (ALSA-2022:7683)\");\n\n script_set_attribute(attribute:\"synopsis\", value:\n\"The remote AlmaLinux host is missing one or more security updates.\");\n script_set_attribute(attribute:\"description\", value:\n\"The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the\nALSA-2022:7683 advisory.\n\n - An issue was discovered in the Linux kernel through 5.16.11.

Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-7683 advisory.\n\n - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information. (CVE-2022-23960)\n\n - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. (CVE-2020-36516)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\n\n - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.\n (CVE-2021-30002)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - A denial of service (DOS) issue was found in the Linux kernel's smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.\n (CVE-2022-0168)\n\n - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)\n\n - In drivers/hid/hid-elo.c in the Linux kernel before 5.16.11, a memory leak exists for a certain hid_parse error condition. (CVE-2022-27950)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state. (CVE-2022-28893)\n\n - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is disabled by default, it could allow an attacker to crash the system or have other memory-corruption side effects. (CVE-2022-2938)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1048)\n\n - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.\n (CVE-2022-28390)\n\n - A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system.\n (CVE-2021-3640)\n\n - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub- component. This flaw allows a local attacker with a user privilege to cause a denial of service.\n (CVE-2022-1184)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer dereference and general protection fault. (CVE-2020-36558)\n\n - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)\n\n - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code. (CVE-2022-2078)\n\n - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor. (CVE-2022-24448)\n\n - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)\n\n - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.\n An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered.

An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to\n influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive\n information. (CVE-2022-23960)\n\n - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the\n hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session\n or terminate that session. (CVE-2020-36516)\n\n - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a\n use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel\n information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)\n\n - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in\n drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.\n (CVE-2021-30002)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow\n an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - A denial of service (DOS) issue was found in the Linux kernel's smb2_ioctl_query_info function in the\n fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user\n function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.\n (CVE-2022-0168)\n\n - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel\n (CVE-2022-20368)\n\n - In drivers/hid/hid-elo.c in the Linux kernel before 5.16.11, a memory leak exists for a certain hid_parse\n error condition. (CVE-2022-27950)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets\n are in the intended state. (CVE-2022-28893)\n\n - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is\n disabled by default, it could allow an attacker to crash the system or have other memory-corruption side\n effects. (CVE-2022-2938)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote\n attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte\n nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers\n concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM\n for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the\n system. (CVE-2022-1048)\n\n - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.\n (CVE-2022-28390)\n\n - A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the\n way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()\n together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A\n privileged local user could use this flaw to crash the system or escalate their privileges on the system.\n (CVE-2021-3640)\n\n - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-\n component. This flaw allows a local attacker with a user privilege to cause a denial of service.\n (CVE-2022-1184)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of\n actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()\n function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This\n flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to\n cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14\n and later versions. (CVE-2022-29581)\n\n - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer\n dereference and general protection fault. (CVE-2020-36558)\n\n - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation\n (CVE-2022-2586)\n\n - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an\n attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and\n possibly to run code. (CVE-2022-2078)\n\n - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way\n user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw\n to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the\n O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a\n regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file\n descriptor. (CVE-2022-24448)\n\n - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain\n privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past\n commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)\n\n - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.\n An attacker with access to a serial port could trigger the debugger so it is important that the debugger\n respect the lockdown mode when/if it is triggered. (CVE-2022-21499)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of\n service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal\n instruction in guest in the Intel CPU.

SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3288-1 advisory.\n\n - The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set. (CVE-2016-3695)\n\n - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session. (CVE-2020-36516)\n\n - Uncontrolled resource consumption in the Linux kernel drivers for Intel(R) SGX may allow an authenticated user to potentially enable denial of service via local access. (CVE-2021-33135)\n\n - A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)\n\n - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub- component. This flaw allows a local attacker with a user privilege to cause a denial of service.\n (CVE-2022-1184)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)\n\n - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:\n A-223375145References: Upstream kernel (CVE-2022-20369)\n\n - kernel: posix cpu timer use-after-free may lead to local privilege escalation (CVE-2022-2585)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)\n\n - A flaw was found in hw. Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-23816) (CVE-2022-28693)\n\n - An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input data. This flaw allows a local user to crash the system. (CVE-2022-2873)\n\n - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data. (CVE-2022-2905)\n\n - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is disabled by default, it could allow an attacker to crash the system or have other memory-corruption side effects. (CVE-2022-2938)\n\n - A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring().\n The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper locking when performing operations on an object. This flaw allows a local user to crash the system or escalate their privileges on the system. (CVE-2022-2959)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - An issue was discovered in the Linux kernel through 5.16-rc6. There is a lack of check after calling vzalloc() and lack of free after allocation in drivers/media/test-drivers/vidtv/vidtv_s302m.c.\n (CVE-2022-3078)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of service can occur upon binding to an already bound chain.
